6 Claims.

My invention relates broadly to electric valve actions and more particularly to an electrically operated organ valve.

This application is a division of my application Serial No. 404,229, led July 26, 1941, for Multiple magnetic valve for organs, now Patent 2,335,311, granted November 30, 1943.

One of the objects ci my invention is to provide a construction of organ valve including a valve member comprising a. multiplicity of alternately disposed layers of relatively soft and relatively stiff laminations carried by a valve actuator and adapted to be moved to open or closed positions for establishing sealing connection with a valve seat.

Another object of my invention is to provide a relatively flexible stack of laminations constituting a valve structure and operative to be shifted by a valve actuator to either open or closed position with respect to a valve seat for silently coni,

trolling an acoustic passage.

Still another object of my invention is to provide an improved stack arrangement of pads for a valve structure carried by a valve actuator and coacting with an acoustic passage' for silently and iirmly closing or opening the acoustic passage.

Other and further objects of my invention reside in a construction of pad for organ valves as set forth more fully in the specicaticn hereinaiter following by reference to the accompanying drawing, in which:

Figure 1 is a perspective view showing the parts which are superimposed upon each other for forming the pad of the valve structure; Fig. 2 is a side elevation of a valve actuator equipped with the pad construction of my invention; Fig. 3 is a plan View taken substantially on line 3--3 of Fig. 2 showing a plurality of valve actuators equipped with pads arranged in accordance With my invention and illustrating the pads in plan view, certain of which have the laminations partially broken away or removed to more clearly explain the construction of the pad; Fig. 4 shows an end view of the valve actuatorsl and pads carried thereby, the view being taken on line 4 5. of Fig. 2 to show the valve seats and associated acoustic passages in section; and Fig. 5 is a vertical sectional view taken on line 5-5 of Fig. 4 showing the valve pad of my invention mounted in position with respect to the valve actuator.

Referring to the drawing in more detail, Figure 1 illustrates the parts of the laminated pad constituting the organ valve of my invention where the parts are illustrated in perspective view in superimposed relation to the armature member and the spring tension device associated therewith. The magnetic armature is represented at 23 having a groove 24 adjacent one end and an angularly disposed portion 25 adjacent the opposite end. A resilient leaf spring member 2'! is apertured at 28 adjacent one end in registry with aperture 26 in the magnetic armature 23. The opposite end of leaf spring 2l is apertured at 3E! for facilitating the mounting of the armature under spring tension as will be hereinafter described. A plate of insulation material 3i which is of elongated contour rounded at each end is apertured at 3io in registry with apertures 25 and 28. The tubular rivet 32 passes through aperi' ture 28 in armature 23 and aperture 28 in resilient plate of insulation material 3| is relatively stiff whereas the resilient pad member 33 is relatively soft. The resilient pad member 33 supports the relatively stiff plate of insulation material 34 which is suitably cemented or glued thereto. The plate of insulation material 34 is shaped to correspond to the shape of the relatively stiff plate of insulation material 3|. The relatively stiff plate of insulation material 34 supports the relatively soft facing pad 35 which is suitably cemented or glued thereto. The soft facing pad 35 is shaped to conform with the contour of the relatively stili plates of insulation material 3| and 34. The soft facing pad 35 forms the sealing means for the port 2 for closing the acoustic passage to the reed pressure box 3 and outlet 4. The peripheral edge of port 2 forms one of the limiting abutments for movement of armature 23 while the opposite limiting abutment is provided by resilient stop 36 carried by the control magnet spool head.

In order that the functioning of the laminated valve structure formed by alternate stili" and soft laminations may be fully understood, it is necessary to describe in some detail the associated parts of the magnetic actuator employed with the valve mechanism oi my invention.

Reference character I indicates the 101655111@ chamber having ports 2 therein leading to the reed pressure box 3, having an outlet indicated at 4. The reed is indicated at 5, mounted at one end on the reed supporting frame 5. As represented in Fig. 4, the several reed pressure boxes 3 are partitioned one from the other for the independent passage or" air therethrough under control of the electric valve action. t will be understood that the electric valve action' orv my invention may be used. for both vacuum. and pres,.- sure arrangements as in the usual pipe organ system, and that the illustration of my invention in association with a reed system is merely for the purpose of illustrating one application of my invention.

The bracket for mounting the several electromagnets is represented at l', secured by suitableV means 8 to the Wall of the pressure chamber' l. The bracket 'I is provided with apertures 9 therein through which a suitable number ci securing.

means 8 may be passed. Perforations is are struck out of the material forming the brackets l and grooves l2 are provided in the material of bracket 1 through which bearing rod H extends. Bearing rod H is spot-welded at opposite ends i4 and i5 in the aligned grooves i2. The bearing rod H. may also be spot-Welded to the material of bracket 'l' intermediate the ends It and I5. Preparatory to the spot-Welding operation the bearing rod l i is retained in position in the aligned grooves i2 by means of tubular rivets I5 which extend through apertures itc in brackets l and secure clamping members i'i over the bearing rod li. After the bearing rod H is thus secured in position it may be spotwelded to the bracket at the ends llii5 and also in intermediate positions i3, is, 20, 2i and 22.

The bearing rod Il, extending transversely across the perforations l is now ready to receive the several rockable armature members which control the electric valve action. .The armatures 23 are mounted With respect to bearing rod I I by slipping the armatures through the perforations- H3 `to positions in which the groove 24 therein receives bearing rod H While leaf spring 2'1 bears against bearing. rod H as show-n more clearly4 in Fig. 5. As heretofore explained, the leaf spring 2l is secured at one end to the armature 23 While the opposite end of the leaf spring is apertured at 3@ to provide a connection for coil spring i5 as hereinafter explained.

The controlV magnet comprises the magnetic core 31 which is secured in aperture 353 in magnetic bracket l. ture 38 in magnetic bracket l and projects therefrom. Spool heads 39 are provided adjacent opposite ends of core 3l and intermediate these spool heads the operating Winding 6I is arranged. The operating Winding M is suitably insulated by a Wrapping of insulation material itl which extends about the magnetic winding Lil. One of the spool heads 39 has a perforated ear 48 extending therefrom with a girdle or band of solder or fusible metalV t9 thereon to provide a terminal for the end of the operating Winding lil. The perforation in ear d8 is shown at 13a form- 'ing a securing, means for the connecting wire which connects the Winding in the circuit. The other end of they operating Winding t! is grounded to the core 3l, as indicated at 53. Circuits to the several electromagnets are thus completed by grounding to bracket i on the one side and by connection of individual wires to the solder girdles or bands t9 on the other side.

The bracket or tongue d2 which forms the connecting means for the coil springl t that tensions the movable armature.. is Welded to the Core 3l' is welded Within apen-` end of core 37 and has a projecting end t3 extending from core 3l. Coil spring E connects between the projecting end i3 of tongue 42 and the apertured end 3Q of leaf spring 2l. The core 3l is suitably shaped at the end il to coact with theiI angularly disposed end 250i rockable armature 23 toinsure'maximum utilizationo the magnetic lines of force which extend around the magnetic circuit established through magnetic core 31, magnetic bracket l, magnetic armature 23 and the shaped end 25 thereof.

As before Vnoted the magnetic bracket 'l is slotted at [it intermediate each of the portions of the bracket which are apertured at 38 so that the magnetic lines of force Which thread the portions of the bracket l are maintained substantially independent and connned to substan-l tially separate paths for controlling the rapid and Various functioning of the several valves Within a small area.

The laminated valve `structure of my invention has many advantages in insuring a sealing connection with the acoustic passage. It will be noted that one relatively rigid or stift pad member is rigidly connected with the valve actuator. The relatively soft and resilient lamination that is carried by the relatively stii lamination constitutes a coupling or intermedio e link member on which the second relatively rigid or stiiI" lamination is mounted. This second rela-- tively sti or rigid lamination carries a, resilient or ilexible facing pad which forms the sealing connection with the acoustic passage. The relatively stiff or rigid laminations are of the same shape and contour and are greater in transverse dimension than the intermediate resilient pad. The relatively stili lamination that is carried by the smaller intermediate resilient pad is accordingly free to be angularly displaced suiciently to eiect a centering and sealing connection with the acoustic passage for effectively closing the passage.

1t will be understood that the electric valve action of my invention may be employed a single unit or may be arranged Yin the multiple coacting units illustrated herein. 'The construction shown has been found to be very practical for manufacture and production and successful in operation. However, although l have described the preferred embodiment of my invention, I realize that modifications be made and I intend no limitations upon my invention other than may be imposed by the scope of the appended claims.
